OnePlus 7 Pro is a great device, but like any other device that is still new on the market, it has a share of its own issues.

So far, we’ve already reported about OnePlus 7 Pro issues with incoming calls and texts on Verizon Wireless, double tap to wake, ghost touches, and a flurry of others, but it seems we ain’t done yet.

We expect OnePlus to solve these problems via a software update in the future but until now, here’s your best shot to fix the issues.

How to fix Wi-Fi and sound issues on T-Mobile OnePlus 7 Pro

Note: This fix requires your T-Mobile OnePlus 7 Pro to be rooted. So don’t do this until you are sure you know what you are doing. You will need to install a custom kernel file to fix the issues with Wi-Fi and sound.

If you are experiencing broken Wi-Fi and sound on your OnePlus 7 Pro, follow the steps below to fix the issues:

So, flashing HolyAngel’s SkyDragon kernel fixes the issue! What I ended up needing to do was formatting data in TWRP, so I could move the kernel zip to internal storage. I also threw Magisk in there. I flashed the kernel, followed by Magisk, and voila! Back in action! Thanks to HolyAngel for suggesting I flash their kernel! You rock

  1. Make sure you have installed TWRP recovery on your OnePlus 7 Pro. (You need to unlock the bootloader of your device to be able to install TWRP.)
  2. Install the fastboot and ADB driver on your PC.
  3. Download the SkyDragon kernel file from > here.
  4. Reboot the device to TWRP recovery.
    1. Power off the device.
    2. Press and hold the volume down and power button together to reboot into recovery mode and access TWRP.
  5. Open the command window in the folder where you have the kernel file. Shift+right click in the empty space and select ‘Open Powershell window here’.
  6. Transfer the kernel file from your PC to cache folder on the OnePlus 7 Pro. Run this command in the Powershell window:
    adb push /cache/
  7. Now, in TWRP, tap on Install button, and then select the kernel file from the cache folder.
  8. Confirm and install it.
  9. When done, tap on Home button > Reboot > System.
